Tolerance time ± SD across the different environmental conditions and work rates (n = 12). Main effect observed for environment (WBGT37 < WBGT30 < WBGT21; P < 0.001), work intensity (5.5 < 4 < 2.5 km·h−1; P < 0.001), and their interaction (P < 0.001). aSignificantly different to the same speed at WBGT 21°C (P < 0.05); bsignificantly different to 5.5 km·h−1 at the same environmental condition (P < 0.05); csignificantly different to 4 km·h−1 at the same environmental condition (P < 0.05); dsignificantly different to the same speed at WBGT 30°C (P < 0.05).
